That brings the estimated investigative and prosecution costs attributed to the case to more than half a million dollars. It also brings the documented cost in public dollars spent on the Casey Anthony case overall to more than $822,470.

The Orange County Sheriff's Office, the lead investigating agency in the case, announced Friday it is seeking reimbursement of $293,123.77 for its role in looking into the disappearance of 2-year-old Caylee Marie Anthony in mid-July 2008, according to just-released figures from the Orange County Sheriff's Office.

"An incredible amount of manpower was deployed and over 6,000 tips were received requiring extensive man hours," Zambouros wrote.

The reimbursement request is based mostly on the Criminal Investigation Division's activities, he noted.

"Otherwise, the reimbursement for cost of investigation would certainly be larger," he wrote.

Also, the reimbursement request deals primary with costs from July 15, 2008 - when Caylee was first reported missing - to Dec. 11, 2008, when her remains were discovered.

Beyond the Orange Sheriff's Office costs, the state attorney's office says the case cost its office $141,362; the Florida Department of Law Enforcement estimated its costs at $71,939; and the Metropolitan Bureau of Investigation attributed $10,645.38 in costs to the case.

The public cost of the Casey Anthony case is actually greater than the $517,071 estimated in prosecutorial and investigative work.

As of earlier this month, the state Justice Administrative Commission said the state had paid out $118,847 for Casey Anthony's defense. Her defense team had actually billed $147,018 for costs, but not all of it was paid out.

Additionally, the Orange County Clerk of Court has provided an initial summary of costs associated with the sequestration and care of the jury for the murder trial. The total costs tallied by the clerk's office as of Friday was $186,904.

Adding the law enforcement cost estimates to the state money paid for the defense and the clerk's tally for the jury costs brings the documented public money spent on the case to $822,821.48.
